question 1 is congruent. 2 is not congruent and 3 is congruent
Answer:
Child tickets are 97
Step-by-step explanation:
x + y = 175 ...............(1)
x = 175 - y
5.90x + 9.10y = 1282.10. .........(2)
5.90 (175 - y) + 9.10y = 1282.10
1032.50 - 5.9y + 9.10y = 1282.10
3.2y = 249.60
y = 249.6. / 3.2
y = 78
From equation 1
x + y = 175
x + 78 = 175
x = 175 - 78
x = 97
Step-by-step explanation:
let eqn be y - y1 = m(x - x1)
m = (9 - 1)/(-3 - (-7))
m = 2
sub (-7, 1):
y - 1 = 2(x + 7)
therefore, the equation is y - 1 = 2(x + 7)

Answer: a. 3.4t (miles)
b. 2.125 miles
c. t = 1.6 hours
Step-by-step explanation:
A) We will use the relation:
Distance = Speed × Time
Distance= 3.4 × t
= 3.4t (miles)
B) If t= 5/8
Distance d= 3.4 × 5/8
= 3.4 × 0.625
= 2.125 miles.
C) If the distance d= 5.44,
Time will be:
d= 3.4t, and we know that d=5.44
Therefore, 5.44 = 3.4t
t = 5.44/3.4
t = 1.6 hours
